• Enabling premium features before migration-Before migrating disk groups and virtual disks, enable the required premium features on the destination storage array. If a disk group is migrated from a MD3200i storage array that has a premium feature enabled and the destination array does not have this feature enabled, an Out of Compliance error message can be generated. Disk Roaming You can move physical disks within an array. The RAID controller module automatically recognizes the relocated physical disks and logically places them in the proper virtual disks that are part of the disk group. Disk roaming is permitted when the RAID controller module is either online or powered off. NOTE: The disk group must be exported before moving the physical disks. Advanced Features The RAID enclosure supports several advanced features: • Virtual Disk Snapshots • Virtual Disk Copy • High Performance Tier NOTE: Virtual Disk Snapshot, Virtual Disk Copy, and High Performance Tier are premium features that must be activated separately. If you have purchased these features, an activation card is supplied that contains instructions for enabling this functionality. Host Server-to-Virtual Disk Mapping The host server attached to a storage array accesses various virtual disks on the storage array through its host ports. Specific virtual disk-to-LUN mappings to an individual host server can be defined. In addition, the host server can be part of a host group that shares access to one or more virtual disks. You can manually configure a host server-to-virtual disk mapping. When you configure host server-to-virtual disk mapping, consider these guidelines: • You can define one host server-to-virtual disk mapping for each virtual disk in the storage array. 50 Planning: MD3200i Series Storage Array Terms and Concepts
